ANTISEP'IIO PRODUCT.

llo Drawing. Application filed August 21, 1925, Serial No. 51,880, andin France June 29, 1925.

The object of my invention is an antiseptic and deodorizing productwhich can be prepared in a pulverulent or compressed state andused'either as a powder or dissolved in water. This product ischemically neutral and is odourless and non-toxic. It can therefore beshipped in any metallic containers either as a powder or dissolvedwithout any danger of corroding the said containers.

It is essentially made out of an intimate lnixture of the followingsalts.

1. Sulfophenate of zinc the Para variety whereof is preferably used. Thesulfophenate of zinc is the bactericid and microbicid agent of theproduct. It is a very powerin] bactericid. Even diluted in a volume ofwater one hundred times greater it kills several species of microbe in avery short time.

.Though it is derived from phenol this salt is odourless, whetherpulverulent or dissolved. It dissolves in water almostinstantaneously'and shows itself clearly as basic, it produces a ellowcolor with methyl orange and a vio et color with litmus. Lastly the zincwhich it contains helps as explained hereunder to stop the bad odoursarisin from fermentation and putrefaction.

b2. nother salt of zinc preferably sulp ate.

3. An alkaline acetate or an acetate dissolving in water withoutproducing a precipitate with the zinc salts used.

The use of the second zinc salt, referably sulphate, is for deodorizing.rough. its metal "it absorbs sulphuretted h drogen and ammoniacal gasesand gives w ite recipitates which do not stain or spoil linen, clothes,hangings, etc. and which can be easily'removed by brushing or otherwise.

The said gases being absorbed, the bad odours arising fromputrefactionand mouldiness disappear at once.

Zinc sulphate, with no iron, is preferably used because it is a non-acidsalt as oposed to zinc chloride. Moreover it afords the great advantageof being-non-hygroscopic which is very important if the product is usedas a powder. The product made up with zinc chloride, for. instance,could not be used in owder, as the zinc chloride is extremely deiquescent and would produce at once, in moist air, a thick paste.

Lastly the zinc sulphate prevents to a certain extent the development ofmicrobes and of bacteriae. i

The acetate used which is an alkaline acetate or an acetate dissolvingin water withis necessary for two purposes viz:

1. It enhances greatly the deodorizing'action of the zinc salt; thesulphuretted hydrogen (H 8) does not precipitate zinc in presence ofacids and in neutral solutions the salts of stron acids are veryincompletely precipitate In both cases, the deodorizing would not-beproduced or would be very incomplete. A chemical uilibrium takes placeand some strong aci is freed whereby the solution becomes very acidaccording to the equation.

. ZnSO,+H,S:ZnS-l-SO,H,.

The strong sulphuric acid formed would allow H S to be disengaged. Theaddition of an acetate, such as sodium acetate makes the reactioncomplete.

' The deodorizing is thus complete.

2. The acetate such as sodium acetate keeps the solution neutral becauseit prevents the formation of a strong acid such as sulphuric,hydrochloric or nitric acid, the weak acetic acid bein disengaged intheir lieu. In the case of zinc chloride, its soluout forming aprecipitate with the zinc salts tion would be made basic by the additionof ortant; objects in metal such as surgical Instruments are notattacked. This neutrality is proved by the reaction of methyl orangewhich remains yellow and of litmus which remains violet whereas bothmethyl oran and litmus would become red if there remained the leastacidity.

By way of example a good result is obtained by either of followmmixtures (for one litre of water'the secon of which may onl be used as asolution).

O,Zn, 711,0 250 gr.

Sodium acetate 20 gr.

Zinc sulphophenate 50 gr. or

Z1101 125 gr.

Sodium acetate 75 gr:

Zinc sulphophenate 50 gr. I

Of course an inert substance can be added to those mixtures such asborax, sea-salt or any antiseptic substance dry or liquid (when asolution is used).

For preparing the dry mixture, the three com nents are crushed and mixedtogether.

the antiseptic product is to be used as a powder, the components should.previously be dried, at 100 C. for instance. If it is to be used in theform of compressed tablets the.drying should only be partial.

The tablets dissolvin entirely in water show the advantage 0 allowingeasily a solution of a given microbicid power to'be made which isespecially useful in the case, of veterinary practice. I

For preparm the mixture under liquid form, it is of a vantage todissolve first the zinc sulphate, then the acetate and last of I all thezinc sulphophenate. This order has closets,

not a great importance however and any otllier order will produce thesame final resu t.

The product constituted by the above described mixture is a verypowerful disin fectant which destroys instantaneously bad odours,besides being a most eifective bactericid which can be used without anyinconvenience for surgical or veterinary purposes. It may be used inhospitals, water breweries, tanneries, slaughterhouses, stables \and thelike. It should generally be used as a spray after ithas been suitablydiluted in water. The solution can also be used for washingthe partswhich are to be disinfected.

What I claim is 1. An antiseptic and deodorizing roduct having aneutralreactionand very so uble in water formed by the mixture of sulphophenateof zinc, of a second zinc salt and of an acetate soluble in water andproducing no precipitate with the zinc salts used.

2. An antiseptic and deodorizing product as claimed inclaim 1 the secondzinc salt of which is sulphate of zinc. 5

3. An antiseptic and deodorizing product as claimed in claim 1 thesulphophenate of zinc of which is of the Para variety.

In testimony whereof I have aflixed my signature.
